Question 20

Write a program that reads characters from the keyboard one by one. All lower case characters get stored inside the file 'LOWER', all upper case characters get stored inside the file 'UPPER' and all other characters get stored inside file 'OTHERS'.

Answer 
lower_file = open("LOWER.txt", 'w')
upper_file = open("UPPER.txt", 'w')
others_file = open("OTHERS.txt", 'w')
ans = 'y'
while ans == 'y':
    char = input("Enter a character: ")
    if char.islower():
        lower_file.write(char + "\n")
    elif char.isupper():
        upper_file.write(char + "\n")
    else:
        others_file.write(char + "\n")
    ans = input("Want to enter a character? (y/n): ")
lower_file.close()
upper_file.close()
others_file.close()
Output
Enter a character: e
Want to enter a character? (y/n): y
Enter a character: A
Want to enter a character? (y/n): y
